5A Lithium Charger CV CC Buck Step Down Power Supply Module LED Driver
Product Description
Size: CC CV Voltage Regulator
Parameter:
Frequency: 180KHz
Weight: about 25g
Input voltage: 4-38V
Output power: 75W(Max)
Transfer efficiency: 96%(Max)
Output current: adjustabel;5A(Max)
Input reverse connection protection: NO
Working temperature: -40 to +85 Celsius
Output voltage: 1.25-36V constantly adjustable
Short-circuit protection: YES(limited current of 8A)
Over-temperature protection: YES(item will stop output atomatically)
Note:
please strengthen cooling when buck converter module is used in more than 3A,35W
Product functions:
1.Work as high-power LED constant current driver module
2.Work as buck converter module with over-current protection
3.Charger of batteries(eg. nickel-cadimium or nickel-metal hydride battery, lithium batteries);can be used in solar panel/wind turbines/etc
How to set current limits:
1. Adjust constant-voltage potentiometer to make output voltage reach the voltage value which you want.
2. Use 10A multimeter to measure short-circuit output current (directly connect two meters to output interface), at the same time, adjust constant-voltage potentiometer to make output current reach preset over-current protection value. (If the current value multimeter displays is 4A, the maxmum current of the module only can be up to 4A; when the current reach 4A, constant-voltage constant-current red indicator light is on, or the light is off)
LED indicator light:
1. Red light is on in constant current status and off in constant voltage status.
2. Blue light is on when charging and off when full-charging
3. Green light is on when full-charged.
Package inclueds:
1pcs Buck Converter
